Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to a steam scraper anti-clogging evaporator. Background Art

[0002] Scraped film evaporator, also known as scraped film concentrator, is widely used in petroleum, chemical, pharmaceutical and other industries. It is particularly suitable for materials with high viscosity, easy crystallization, scaling and heat sensitivity. The evaporator is a very important component among the four major parts of refrigeration. The low-temperature condensed liquid passes through the evaporator to exchange heat with the outside air, vaporize and absorb heat to achieve the refrigeration effect.

[0003] After searching, the application with patent number CN204093064U discloses a scraped thin film evaporator, including an evaporator cylinder, a separation cylinder arranged on the evaporator cylinder and a transmission device arranged on the separation cylinder. A heating jacket is arranged on the outer wall of the evaporator cylinder, and a steam inlet and a condensed water outlet are arranged on the heating jacket. A rotating shaft and a scraper are arranged in the evaporator cylinder. The rotating shaft passes through the separation cylinder and is fixedly connected with the transmission device. The separation cylinder is provided with a distributor, a gas-liquid separator and a steam chamber from bottom to top. The material can be evenly sprinkled on the inner wall of the evaporator cylinder through the distribution plate to improve the evaporation efficiency.

[0004] However, due to the setting of the evaporator cylinder, the front end of the evaporator cylinder lacks a filtering component, and pollutants can easily enter the evaporator cylinder, causing the evaporator to be blocked, affecting the use effect and life of the evaporator. At the same time, after the filter has been used for a period of time, impurities can easily adhere to the surface of the filter and cause the filter to be blocked. The impurities on the filter are not easy to clean, resulting in poor air intake effect and affecting the efficiency of the evaporator.

[0005] Therefore, we proposed the steam scraper anti-clogging evaporator. Summary of the invention
